IMPROVEMENT IN CAR-HEATING APPARATUS.

Specification forming part of Letters Patent No. 195,792, dated October2, 1877; application filed September 1, 1877.

To all whom it may concern:

Be it known that I, JAMEs F. OALLAWAY, of Louisville, in the county ofJefferson and State of Kentucky, have invented a new and ImprovedRailway Car Heating Apparatus and I do hereby declare that the followingis a full, clear, and exact description of the same.

The object of my invention is to provide an improved apparatus forheating all classes of railway passenger-cars by steam derived from thelocomotive-boiler. The mode of applying the apparatus is shown in theaccompanying drawing, in which- Figure 1 is a side elevation of afragment of a locomotive and tender with my apparatus attached. Fig. 2is a side elevation, and Fig. 3 a horizontal section, of a fragment of apassenger coach or car.

The pipe A, for conducting steam-from the locomotive-boiler B to theseveral passenger cars or coaches of a train, is suitably connected withthe steam-dome 0, passes thence underneath the tender 0, and extendsalong the bottom of each coach 1), Figs. 2 and 3.

Between the locomotive and tender, and between each two coaches, Iemploy a flexible connection, consisting of a rubber pipe, (6,131'0-vided with suitable couplings, b, which admit of convenient attachmentand detachment, for the purpose of coupling and uncoupling the cars, asoccasion may require.

The' admission of steam to pipe A is controlled by the engineer, throughthe medium of the rod or lever c, which extends into the cab andoperates a "alve or cock, d. The steam may be shut off from each coach,when required, by a rod, 0, and valve f, located in one corner of thelatter, as shown. Another rod and "alve, g h, control the escape of thewater condensed from steam, the said valve being located at a downwardcurve or bend, i, of the pipe A, extending below the floor or bed, at ornear each of two diagonally-opposite corners of a car. The main pipe Aextends along the sides or middle of the cars, and short branches orconvolutions E extend laterally therefrom beneath each seat, or whereverelse it may be desired to apply a special degree of heat.

I do not claim a steam-heating pipe traversing the floors of cars, andhaving a flexible connection between the cars; but

What I claim is- In a railway-ear heating apparatus, the steam-pipe A,leading from the dome of the 10- comotive, and traversing the floor ofthe cars, and having a downward curve, 6, below the floor, a valve, h,located in the curve, its rod 9 extending up into the car, and the valveand rod f e, the respective valves allowing escape of water ofcondensation, and controlling admission of steam, all combined,constructed, and arranged as shown and described.
